Final Project: Interactive Device for Autistic Children

Design Purpose:

• Targeting autistic children
• Conduct cognitive training through fun interaction
• Enhance concentration via multi-sensory feedback
• Alleviate anxiety and coordinate limbs

Key Points:

• Autistic children are attracted to sensory stimuli like light, shadows, and bright colors
• Interactive installations use lights, sounds, and touch to attract attention
• Through play, they gradually improve focus, reduce unusual behaviors, and learn social interaction
• Design principles from mature international devices: rounded shapes, cool colors, diverse materials, simple operation, immediate audio-visual feedback
• Author created a line-tracing device: lights up when correct path is traced, supports two-player interaction

Key Points:

• Autistic children fear noise and strong light; environmental changes cause anxiety
• Rehabilitation room design: soft lighting, sound insulation, stable furniture placement, avoid stimulation sources
• Stabilize children's emotions through environment control
• Zoned spaces: private corners for solitude and interactive areas for play
• Future direction: intelligent, personalized environments that adjust in real-time based on each child's state

Key Points:

• Autistic children struggle with emotion recognition, fear audio-visual stimuli, lack social skills
• Traditional single-sensory training has poor effectiveness
• This product combines visual, auditory, and tactile senses with emotional design
• Collects physiological data and provides real-time emotional feedback
• Examples: VR scenarios, smart tactile clothing, interactive toys, brain-computer interfaces
• Uses light/shadow, vibration, and sound effects to help children perceive emotions
• Future: personalized smart devices balancing cost, privacy, avoiding over-dependence on machines

Key Points:

• Focuses on designing an emotion-monitoring, deep-touch-pressure, and acupoint-massage smart vest
• Tactile soothing is an effective calming method
• Core capabilities: physiological monitoring and automatic pressure therapy
• Existing smart clothing focuses on social obstacle training; few products target anxiety relief
• Most have simple structures, lacking multi-module integrated design
• Three core technologies: anxiety recognition, DTP (Deep Touch Pressure therapy), acupoint massage
• Vest includes: physiological monitoring module, acupoint massage module, central control module, automatic air pump for precise pressure control

Key Points:

• Based on ABA (Applied Behavior Analysis) theory
• Targets social and perceptual development deficits in autistic children
• Cactus-shaped multi-sensory cognitive training toy
• Integrates ABA stimulus-response principle, DTT discrete trial teaching, and color psychology
• Uses warm/cool color grading training and positive rewards for behavioral intervention
• Main body: cactus bionic shape with multi-material, multi-size thorn-like protrusions
• Provides graded tactile stimulation from weak to strong
• Built-in LED lights for visual feedback
• Three-tier cognitive cards:初级实物识图 (basic object recognition), 中级色彩场景 (intermediate color scenes), 高级社交情景 (advanced social scenarios)
• Interaction logic: tactile + visual + voice multi-modal closed-loop interaction
• Correct operation triggers light reward; errors receive voice guidance
• Modular structure adapts to home, institutional rehabilitation, and social simulation scenarios

Key Points:

• Based on embodied cognition theory
• Addresses sensory sensitivity and social weakness in autistic children
• Combines advantages and disadvantages of traditional painting therapy
• Proposes VR painting therapy design solution
• VR advantages: immersive, safe, customizable, 3D interaction
• Paired with gesture devices, soft visuals, and multi-sensory interaction design
• Constructs complete therapy system, providing design reference for autism art rehabilitation

Key Points:

• Selected 15 autistic children aged 6-10 for 12-week AR motion-sensing game intervention experiment
• Used PDMS-2 and SRS scales to compare data from motor and social dimensions
• Results: motion-sensing games significantly improved gross motor skills and overall social abilities
• Reduced stereotyped behaviors
• Only optimized visual-motor integration; limited effect on fine motor skills like grasping
• Confirmed AR motion-sensing as effective rehabilitation intervention method
• Future: optimize game content to strengthen fine motor training

Key Points:

• Based on five-sense healing theory
• Addresses homogeneous rehabilitation spaces lacking local culture and emotional design
• Integrates traditional shadow puppetry intangible cultural heritage elements into space design
• Implements spatial strategies across five sensory dimensions: visual, auditory, tactile, olfactory, gustatory
• Visual healing: low-saturation cool-tone shadow puppetry colors
• Auditory-tactile linkage: shadow puppetry tactile modules linked with sound effects
• Olfactory environment: aromatic plants + seasonal spices
• Gustatory healing: interactive food education spaces
• Forms rehabilitation space design combining therapeutic function with traditional culture

Core Features:

1. Distance Sensor Line-Tracing: Children trace shapes or lines along grooves. Correct completion triggers positive light feedback, guiding hands-on practice to improve concentration.
2. Heart Rate Monitoring: Real-time monitoring via heart rate sensor. When children squeeze the light bulb, breathing effects display according to heartbeat speed, allowing observation of emotional fluctuations to adjust training rhythm.
3. Gamified Interaction: Reduces resistance through game-like interaction format.
4. Positive Reinforcement: Enhances concentration through positive incentives.

Design Benefits:

• Alleviate anxiety
• Coordinate limbs
• Improve concentration
• Reduce resistance
• Positive reinforcement approach
